Exactly. The biggest hurdle to getting new FOSS off the ground is adoption. It’s really hard to gain inertia when the vast majority of users refuse to switch. When they already know how to use the closed-source version, they’ll be resistant to change. Even if the closed-source version is less user friendly and more annoying to use, people will still continue to use it because they don’t want to start learning something new. Unity did Godot a massive favor, by scaring all of their users away and leading them straight into Godot’s open arms.

It would be like if Microsoft did something stupid enough to cause 50% of Windows users to switch to Linux overnight. Even if Microsoft later rolled those changes back, a lot of users have already installed (and started to learn) Linux, and aren’t going to go through the trouble of switching back again. And by that point Linux will have an established user base and will be able to maintain and grow that population much easier.
